Fashion is where money is. The public has grown so obsessed with Hollywood that encourages the fashion industry to evolve on its lucrative growth. Instant popularity is at hand if you have the right combination of everything (say right choice of endorser, right choice of fashion ideas, innovative and creative sense of fashion and the likes).
Nonetheless, the fashion industry is a hard business to penetrate. You must be equipped with the knowledge and influences that would provide you the maximum exposure you need to deliver your creations into the industry. But still, most of everything is commanded by your brilliance in designing that would give you center stage.

Your talent might be there. It is an innate property that can't be stolen from you. It is in your own discretion though to let that talent turn into passion. But talent and skills are not enough. You have to undergo formal instructions to be able to hone those special features and direct them specifically towards becoming the best of your self.

This is the basic principle why fashion schools exist and continue to serve budding artists. They provide guidance and supplemental training to drive the artist to achieve with his creations. While online fashion schools have been gathering fame in the fashion industry, this still does not negate the fact that hands-on training and face-to-face instructions can't be equaled even by the best online degree offers.
Since you are considering entering a fashion school, it is expected of you to be knowledgeable enough on the fundamentals of fashion designing and basic awareness on designing. However, this is not an implication that the student must produce ramp-quality creations initially. Instead, you are expected to bring out the brilliance in simple designs and create concepts that you may have patterned on the works of some great fashion designers or better yet, designs of your own concepts.
Remember that fashion designers only make name in the industry when they have produced something genuinely creative that can cater the present fashion sense while having the originality and good sense of distinction from other fashion trends.
You may not be possessing this nature for the moment. But the thing is, an efficient fashion school could best bring out the brilliance in you and in your creations. Initially, you may be producing rubbish concepts but this would be set off with good learning you have acquired from a formal school.

Some people may contend that even without proper education, an artist can create fashion trends that will be embraced by the public. Yes, that might be true. But remember that there are too few individuals who have made it into the fashion scene with the littlest formal study. Besides, even the trends in fashion change. What may have been true before cant be exactly true now. A formal schooling would update you of the most recent trends and the analysis of past styles that have recreated the industry.
A fashion school, like tertiary education will help you seek out your niche. You might have creative ideas lurking in your mind but these free-flowing ideas would be turned into nothing if not properly directed.
Moreover, the experiences of instructors in the fashion schools would be passed down on you. Thus, you are less likely to fall into the same pitfalls they have arisen from themselves.
